Local Environmental Conditions
Woodland and open grassland share the area around this site in Berry Creek. The surrounding woodland makes trees an important local pollen source. There is plenty of grass pollen here too. Roadside verges and patches of open ground provide further room for grasses and weeds. Clearings, tracks and woodland edges let grasses and other flowering plants grow among the trees.
Tree pollen comes first, peaking in mid-spring. Grasses take over in late spring, with temperatures around 15°C, and their pollen lingers into early fall. A smaller weed peak follows from early summer into early fall. Rain is heaviest in winter, often giving short breaks from high pollen levels. By early winter, as temperatures fall to around 5°C, pollen levels are low again.

Does pollen in Berry Creek come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Berry Creek based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Berry Creek, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.
